Program info
Dirac is a software tool for field or laboratory acoustics engineers. It measures impulse responses and calculates various room acoustical parameters, according to the ISO 3382 and IEC 60268-16 standards. Dirac supports a wide variety of measurement configurations. Dirac will work with most Windows compatible sound devices. A full-duplex card is recommended. USB based sound devices, such as the Triton, can also be used. Dirac is very easy to use, yet provides all the features you may need for your measurements. The automated sound device calibration ensures that you will get the optimum results from your system without having to manipulate your soundcard's controls. Using only a laptop computer, a blank pistol and a microphone/amplifier-set or SPL meter with AC output, you can obtain a large number of parameters such as the sound strength G, the early decay time EDT, the reverberation times T10, T20, T30, Tx, and the energy ratios C30, C50, C80, Cx, D50, Dx, H and Ts.
